AdLoad malware is still infecting Mac systems years after its first appearance in 2017. AdLoad, a package bundler, has been observed delivering a wide range of payloads throughout its existence. During AT&T Alien Labs’ investigation of its most recent payload, it was discovered that the most common component dropped by AdLoad during the past year has been a proxy application turning MacOS AdLoad victims into a giant, residential proxy botnet.

A study into the feasibility of hacking low-Earth orbit satellites has revealed that it's worryingly easy to do.

In a presentation at the Black Hat security conference in Las Vegas, Johannes Willbold, a PhD student at Germany's Ruhr University Bochum, explained he had been investigating the security of satellites. He studied three types of orbital machinery and found that many were utterly defenseless against remote takeover because they lack the most basic security systems.

A US cybersecurity advisory panel will investigate risks in cloud computing, including Microsoft Corp.’s role in a recent breach of government officials’ email accounts by suspected Chinese hackers, according to two people familiar with the matter.
The Cyber Safety Review Board, which was created by the Biden administration to investigate major cybersecurity events, will focus on risks to cloud computing infrastructure broadly, including identity and authentication management, and will examine all relevant cloud service providers, according to a Department of Homeland Security official. The issue was brought into focus by the breach of Microsoft’s email systems, the official said. Both people asked not to be named so they could discuss sensitive information.

MoustachedBouncer is a cyberespionage group discovered by ESET Research and first publicly disclosed in this blogpost. The group has been active since at least 2014 and only targets foreign embassies in Belarus. Since 2020, MoustachedBouncer has most likely been able to perform adversary-in-the-middle (AitM) attacks at the ISP level, within Belarus, in order to compromise its targets. The group uses two separate toolsets that we have named NightClub and Disco.

  • We analyzed Tencent’s Sogou Input Method, which, with over 450 million monthly active users, is the most popular Chinese input method in China.
  • Analyzing the Windows, Android, and iOS versions of the software, we discovered troubling vulnerabilities in Sogou Input Method’s custom-designed “EncryptWall” encryption system and in how it encrypts sensitive data.
  • We found that network transmissions containing sensitive data such as those containing users’ keystrokes are decipherable by a network eavesdropper, revealing what users are typing as they type.
  • We disclosed these vulnerabilities to Sogou developers, who released fixed versions of the affected software as of July 20, 2023 (Windows version 13.7, Android version 11.26, and iOS version 11.25).
  • These findings underscore the importance for software developers in China to use well-supported encryption implementations such as TLS instead of attempting to custom design their own.

Imagine being able to sit behind a hacker and observe them take control of a computer and play around with it.

That’s pretty much what two security researchers did thanks to a large network of computers set up as a honeypot for hackers.

The researchers deployed several Windows servers deliberately exposed on the internet, set up with Remote Desktop Protocol, or RDP, meaning that hackers could remotely control the compromised servers as if they were regular users, being able to type and click around.

As interest in leveraging LLMs has increased in recent months, the Dropbox Security team has been advising on measures to harden internal Dropbox infrastructure for secure usage in accordance with our AI principles. In particular, we’ve been working to mitigate abuse of potential LLM-powered products and features via user-controlled input.
